The invention belongs to the technical field of overall design of airplanes, and relates to a flight propeller safety control system and method, and the system comprises a flight control computer, an ignition controller, an unlocking and ignition device, an airborne storage battery and a propelling device. A first ignition power supply loop and a second ignition power supply loop which are arranged in parallel are arranged between the propelling device and the ignition controller, the number of the ignition power supply loops is two, the two sets of ignition power supply loops are connected with the two sets of safety state switching actuators respectively, and the first ignition power supply loop and the second ignition power supply loop are each provided with a mechanical safety pin fixed to an aerial carrier hanging frame. An ignition loop switch is formed; when the aircraft is thrown from the aerial carrier, the mechanical safety pin is separated from the aerial carrier hanging frame, and the first power supply ignition loop and the second power supply ignition loop are connected at the same time. After the separation switch and the inertial navigation assembly respectively send out a separated instruction and flight attitude information and send the separated instruction and the flight attitude information to the ignition controller, automatic program ignition is performed, so that the stability of ignition is effectively realized.

    本申请属于飞机总体设计技术领域,为一种飞行推进器安全控制系统及方法,包括飞控计算机、点火控制器、解锁及点火装置、机载蓄电池和推进装置。推进装置与点火控制器之间设有并行设置的第一点火供电回路和第二点火供电回路,点火通电回路共有两组并且分别与两组保险状态切换作动器,第一点火供电回路和第二点火供电回路上均设有固定于载机挂架上的机械式保险销,形成点火回路开关;当飞机从载机上投放后,机械式保险销与载机挂架分离,第一供电点火回路和第二供电点火回路同时接通。在分离开关和惯导组件分别发出“已分离”指令和飞行姿态信息并发送点火控制器后,进行程序自动点火,从而有效实现点火的稳定性。
